Sosreport - Red Hat ENTERPRISE LINUX 5.5 - TECHNICAL NOTES Manual

Chapter 1. Package Updates
* the useradd utility did not reset the error number variable before checking function return values.
As a consequence, error numbers could be affected by retained values, and the utility would fail with
'invalid numeric argument'. The error number variable is now reset before each function call, and error
numbers in the useradd utility are reported correctly.
* the useradd utility handled the creation of UIDs differently on x86 and PowerPC 64 architectures
than it did on others. As a consequence, UIDs greater than 2147483647 were rejected on these
systems. The useradd utility now treats UIDs the same across architectures, and large UIDs are not
rejected on x86 and PowerPC 64 architectures.
* the usermod utility allows a user account to be modified. The usermod utility did not support LDAP
(Lightweight Directory Access Protocol) users, despite support in other utilities. As a result, the
usermod utility could not add LDAP users to local groups. LDAP support has now been added to the
usermod utility, and LDAP users can be added to local groups.
* the restorecon command sets file security contexts. The usermod utility was calling the restorecon
command every time a user's home directory was changed. This would result in an error if expected
files no longer existed. The restorecon command is no longer called by the usermod utility, and
changing a user's home directory succeeds as expected.
* the faillog utility displays failure logs and sets login failure limits. When the utility was used with
the print option (-p), the log was read sequentially to print in UID order. This was unnecessary and
caused long print times. The faillog utility has been updated to print without ordering, and printing now
completes in an acceptable time.
* the grpconv utility converts shadow passwords and groups. The utility was not checking whether
duplicate group entries existed in the /etc/group directory. Running the utility with duplicate entries
would consume too much memory. The grpconv utility now checks for duplicate group entries in the /
etc/group directory, and excess memory is no longer consumed.
All users of shadow-utils are advised to upgrade to this updated package, which resolves these
issues.

1.190.1. RHBA-2010:0201: bug fix and enhancement update
SOS is a set of tools that gathers information about system hardware and configuration. The
information can then be used for diagnostic purposes and debugging. SOS is commonly used to help
support technicians and developers.
This update includes the following fixes:
• when kmod-gfs2 was installed on a Red Hat Enterprise Linux 5 system, it was possible to have a
situation whereby its version of gfs2.ko would take precedence over that supplied with the kernel.
As a consequence, the wrong version of the Global File System would be used and it also would
be incorrectly set to weak-update. SOS has now been modified to warn system administrators if
